[0016] Figure 5 This is a block diagram of an example computer system in which embodiments of this disclosure may operate. Detailed Implementation
[0017] Various aspects of this disclosure relate to a temperature control assembly for an electronic system. During conventional thermal testing, electronic devices may be placed in a chamber (i.e., a furnace) that tests the devices under various temperature conditions. For example, a single chamber may be used to test components of multiple memory subsystems simultaneously at a specific temperature. Hot or cold gases may be pumped into the chamber to control the temperature of the chamber and the electronic devices therein. The testing process may indicate various operations to be performed on the electronic devices at a specific temperature. Such operations may include, but are not limited to, read, write, or erase operations. The performance and behavior of the electronic devices can be observed or measured while the testing process is being performed. For example, performance characteristics (e.g., read or write latency) and reliability of data stored on memory components may be measured and recorded during the testing process. However, because the chamber can only apply a single temperature to all electronic devices at any given time, testing the electronic devices at many different temperatures can be time-consuming, as a testing process will need to be performed for each desired temperature. Furthermore, all components of the system within the chamber are controlled to the same temperature, and in some cases, only a subset of the system's components need to be tested at a particular temperature. Additionally, only a single testing process can be performed at a time within the chamber. Therefore, if the testing process for an electronic device requires many different conditions, performing different tests on the electronic device under different operating conditions (e.g., different temperatures) can take a lot of time.
[0018] A thermoelectric component (TEC) (also known as a "thermoelectric cooler") converts electrical energy into heat energy and vice versa. A TEC may consist of two surfaces. When a voltage potential is applied to the TEC, one surface heats up while the other surface cools down simultaneously. In some conventional systems, thermoelectric components can be directly applied to objects such as one or more electronic devices in an electronic system to change the object's temperature. However, in some cases, the TEC's shape is not conducive to transferring heat energy to one or more electronic devices. Additionally, in some cases, applying a single TEC to an electrical device may not transfer sufficient heat energy to meet the temperature testing range of some thermal testing conditions. Furthermore, an electronic system may contain multiple electronic devices coupled to a circuit board. These multiple electronic devices may have different vertical heights. Using one or more planar TECs to contact all or a desired subset of the electronic devices may not be feasible.
[0019] In some conventional systems, two TECs of different sizes can be stacked directly on top of each other to remove excess heat. However, in addition to the challenges mentioned above, stacking two TECs on top of each other can be inefficient and often insufficient to transfer enough heat to meet the temperature testing range of electrical installations.
[0020] Various aspects of this disclosure address the above and other challenges by providing temperature control components implemented and coupled to one or more TECs in a heat-conducting layer. The heat-conducting layer includes a bottom surface comprising planar regions. These planar regions of the heat-conducting layer can be positioned above one or more electronic devices in an electronic system to transfer heat to those devices.
[0021] In some embodiments, the bottom surface of the heat-conducting layer includes one or more notched regions. Planar regions intersect with the notched regions. The notched regions include voids or air gaps such that the notched regions are not thermally coupled to electronic devices directly beneath them. The planar and notched regions of the bottom surface of the heat-conducting layer allow temperature control components to transfer heat to some of the electronic devices in the electronic system while isolating other electronic devices from heat transfer.
[0022] In some embodiments, planar regions of the thermally conductive layer may be coupled to a thermal pad. In some embodiments, the thermal pad is compressible and thermally conductive. The thermal pad allows temperature control components, particularly planar regions of the thermally conductive layer, to be thermally coupled to electronic devices with different vertical heights.
[0023] In some embodiments, the temperature control assembly includes an upper TEC, which includes a top surface and a bottom surface. The temperature control assembly also includes a heat transfer assembly, which includes a top surface and a bottom surface. The bottom surface of the upper TEC is coupled to the top surface of the heat transfer assembly. The temperature control assembly includes a lower TEC. The top surface of the lower TEC is coupled to the bottom surface of the heat transfer assembly. The temperature control assembly includes a heat-conducting layer having a top surface and a bottom surface. The top surface of the heat-conducting layer is coupled to the bottom surface of the lower TEC. The bottom surface of the heat-conducting layer includes a planar region positioned above two or more electronic devices of the electronic system to transfer heat energy at the electronic devices.
[0024] The advantages of this disclosure include, but are not limited to, providing a temperature control component that allows for efficient heat transfer between the temperature control component and one or more electronic devices in an electronic system. Furthermore, multiple temperature control components can be implemented to independently control the thermal conditions at the respective electronic systems, allowing for more efficient testing of electronic devices under varying thermal conditions. Additionally, aspects of this disclosure can apply thermal conditions over a wider and lower temperature range than conventional testing systems. Many different tests on electrical devices can be performed more quickly, and the reliability of electrical devices can be improved because any potential defects or flaws can be identified and subsequently addressed in the design or manufacture of the electrical device.
[0025] Figure 1This illustration depicts an example environment for allocating test resources to perform tests on electronic devices, such as memory components, according to some embodiments of the present disclosure. Test platform 100 may include one or more racks 110A, 110B, and 110N. Each of racks 110A, 110B, and 110N may include multiple frames 120, each frame 120 containing one or more thermal chambers. Test platform 100 may include any number of racks or thermal chambers.
[0026] In some embodiments, a thermal chamber may enclose an electronic system within its cavity. The electronic system may have one or more electronic devices. In some embodiments, multiple electronic devices are coupled to a circuit board to form the electronic system. In some embodiments, the electronic devices may be discrete components housed in a package (e.g., a ceramic encapsulation material). The encapsulation material may have external pins, solder bumps, or terminals that connect on-chip or die-on components to off-chip or off-die components (e.g., power supplies, other components on the circuit board, etc.).
[0027] As shown, frame 120 may include one or more thermal chambers. For example, frame 120 may include a first thermal chamber 121, a second thermal chamber 122, and a third thermal chamber 123. Although three thermal chambers are shown, frame 120 may include any number of thermal chambers. Additionally, each thermal chamber may be fitted with a temperature control component for applying temperature conditions to one or more electronic devices within an electronic system. For example, the temperature control component may be thermally coupled to the package of an electronic device in a memory subsystem to adjust the package temperature or die temperature to a desired temperature value within a temperature range. In some embodiments, the temperature control component may be used to apply a localized temperature to a corresponding electronic device in a particular electronic system, a temperature different from the temperature applied by another temperature control component to other corresponding electronic devices in another electronic system located at the same or different frames 120. For example, a first temperature control component may apply a temperature of -20 degrees Celsius to an electronic device in a particular memory subsystem, and another temperature control component located adjacent to the first temperature control component may apply a temperature of 100 degrees Celsius to other electronic devices in another memory subsystem located at the same frame 120.
[0028] In some embodiments, the temperature control component may include one or more thermoelectric elements (TECs). In some embodiments, the temperature control component including one or more TECs may utilize the Peltier effect to apply heating or cooling effects to electronic devices of an electronic system coupled to the temperature control component. For example, the bottom portion of the temperature control component may be coupled to the package of the electronic device of the electronic system to transfer heat energy to and from the electronic device. In some embodiments, the thermoelectric element may be a Peltier device. In some embodiments, the thermoelectric element may include an array of alternating n-type and p-type semiconductors disposed between two plates, such as two ceramic plates. A voltage applied to the thermoelectric element causes one plate to cool while the other plate heats up.
[0029] As shown, each test rack 110A, 110B, and 110N may include multiple frames 120. Each of the frames 120 in a particular test rack may be coupled to a local test component. For example, each test rack 110A, 110B, and 110N may include local test components 111A, 111B, and 111N, respectively. Each of the local test components 111A, 111B, and 111N may receive instructions to perform a test or a portion of a test to be performed in the thermal chamber of the respective test rack. For example, a resource allocator component 130 may receive (e.g., from a user) the conditions of the test to be performed, and the resource allocator component 130 may determine a specific thermal chamber on a different frame 120 in one or more of the test racks 110A, 110B, and 110N that can be used by the test. In some embodiments, the resource allocator component 130 may be provided by a server 131. In some embodiments, server 131 is a computing device or system coupled via a network to local test components 111A, 111B, and 111N.
[0030] Temperature control components for each thermal chamber 121, 122, and 123 of each frame 120 can be used to apply different temperature conditions to the corresponding electronic system. Furthermore, a communication channel can be formed between each electronic system in each thermal chamber and the server 131. For example, the server 131 can control each electronic system so that each electronic system performs different operations under different thermal conditions.
[0031] Resource allocator component 130 may receive test input from a user. The test input may specify the conditions for a test to be performed using one or more electronic systems. For example, the test may specify specific temperature conditions to be applied to a memory component of a memory subsystem, and a sequence of operations to be performed on the memory component under those specific temperature conditions. Resource allocator 130 may retrieve a data structure that identifies available thermal chambers on test platform 100 and the characteristics of those chambers and the electronic systems therein. Resource allocator component 130 may then assign a thermal chamber at test platform 100 containing electronic devices (e.g., embedded memory components) that match or satisfy the test conditions. Resource allocator component 130 may then transmit instructions to a local test component containing the thermal chamber to be tested.
[0032] In some embodiments, a hot chamber may include one or more ports. The one or more ports may expose a chamber within the hot chamber. Electronic devices of an electronic system may be accessed from the one or more ports. In some embodiments, the one or more ports are configured to receive a temperature control component. In some embodiments, the bottom portion of the temperature control component extends within the chamber of the hot chamber and is coupled to a corresponding electronic device. For example, the top portion of a temperature control component, such as a heat sink, may extend above the hot chamber. In some embodiments, the temperature control component may be coupled to the hot chamber. In some embodiments, the hot chamber may be used to hold the temperature control component in place. In some embodiments, the hot chamber may align the temperature control component with a corresponding electronic device such that the bottom portion of the temperature control component can be coupled to the corresponding electronic device. Multiple temperature control components may simultaneously apply different temperatures to the electronic system within the hot chamber. The following at least relates to... Figures 3A to 3B and Figures 4A to 4B Further description of the thermal chamber.
[0033] Figures 2A to 2D A temperature control component according to some embodiments of the present disclosure is shown. Figure 2A A temperature control component is shown in a folded view according to some embodiments of the present disclosure. Figure 2B A temperature control component is shown in an enlarged view according to some embodiments of the present disclosure. Figure 2C Alternative temperature control components are shown in a folded view according to some embodiments of the present disclosure. Figure 2DAnother alternative temperature control assembly is shown in a folded view according to some embodiments of the present disclosure. For illustrative purposes and not for limitation, the temperature control assembly 200 is shown as having several elements. In other embodiments, the temperature control assembly 200 may include the same, different, fewer, or additional elements. For illustrative purposes and not for limitation, the temperature control assembly 200 is shown having relative positional relationships, such as top, bottom, front, and end. It can be noted that other positional relationships are assigned to the temperature control assembly 200 and its elements within the scope of this disclosure.
[0034] A thermoelectric component (TEC) (also known as a “thermoelectric cooler”) converts electrical energy into heat energy and vice versa. A TEC may comprise two surfaces. When a voltage potential is applied to the TEC, one surface heats up while the other, opposite surface, cools down simultaneously. The heat generated by the TEC at one surface can be more than the heat dissipated by the TEC at the opposite surface. For example, for every 1 degree Celsius decrease in temperature at the first surface of the TEC, approximately 3 degrees Celsius is generated at the opposite surface. Because the TEC generates disproportionate heat for each degree of cooling, removing more heat from one surface while cooling an electronic device with the opposite surface can be challenging. This challenge is particularly acute when testing electronic devices at extremely low temperatures, as the heat generated is multiples of the heat removed. In some embodiments, a single TEC may not be sufficient to transfer enough heat to meet the temperature testing range of the electronic device. In other embodiments, a single TEC may be sufficient to achieve the desired thermal testing conditions. In some embodiments, one or more TECs may be implemented, and the number and location of the TECs may be determined, for example, based on design considerations and the desired thermal testing conditions.
[0035] In some embodiments, the temperature control assembly 200 includes a thermoelectric component (TEC) 202. In embodiments, a TEC such as TEC 202 may act as a heat pump to deliver heat to or remove heat from a surface. TEC 202 includes two surfaces 204, namely a top surface 204A and a bottom surface 204B. For example, a TEC such as TEC 202 is configured to simultaneously raise the temperature of the top surface (e.g., top surface 204A) and lower the temperature of the bottom surface (e.g., bottom surface 204B) based on a voltage potential applied to the TEC, or simultaneously lower the temperature of the top surface (e.g., top surface 204A) and raise the temperature of the bottom surface (e.g., bottom surface 204B). In some embodiments, TECs such as TEC 202 and TEC 210 include a set of wires to couple the voltage potential to the TEC and deliver the necessary current to the TEC. The heat removed or delivered to the surface may be controlled by the surface area of the TEC and / or the power supplied to the TEC. For example, if the heat transfer capacity of TEC 210 is twice that of TEC 202, then the surface area of TEC 210 can be twice that of TEC 202, such that the heat transfer capacity of TEC 210 is at least twice that of TEC 202. Alternatively, TEC 210 can have a similar surface area to TEC 202, but be supplied with twice the power and have twice the heat transfer capacity.
[0036] In one embodiment, the temperature control assembly 200 includes a TEC 210. The TEC 210 may include two surfaces 212, such as a top surface 212A and a bottom surface 212B. In one embodiment, the bottom surface 212B is coupled to the top surface 208A of the heat transfer assembly 206.
[0037] In some embodiments, the surface areas of TEC 210 and TEC 202 may have any ratio (e.g., 1:1, 2:1, 1:2, etc.). In some embodiments, TEC 210 has a larger surface area than TEC 202. In some embodiments, TEC 210 is sized to efficiently transfer heat away from TEC 202 under desired thermal conditions.
[0038] In some embodiments, one or more of TEC 210 or TEC 202 may comprise one or more TECs. For example, TEC 202 may comprise two additional TECs distributed above the heat conduction layer 214 and coupled to the heat transfer assembly 206. In some embodiments, a single-level TEC may be implemented. For example, in some embodiments, TEC 210 and heat transfer assembly 206 are not implemented, and TEC 202 may be coupled to surface 222B of the heat sink 220. TEC 202 may comprise any number of TECs at the specific level.
[0039] For illustrative purposes and not for limitation, TEC 202 and TEC 210 are shown in specific shapes. In some embodiments, one or more of TEC 210 or TEC 202 may be of any shape or size, such as a circular TEC, a rectangular TEC, a square TEC, etc. In some embodiments, the shape of one or more of the selected TECs may be based on the surface shape of electronic device 250 or the shape of electronic system 252. Electronic devices 250A to 250E are generally referred to herein as "electronic device 250". For example, if electronic system 252 is rectangular in shape, with multiple electronic devices aligned in a row, then rectangular TECs (at least for TEC 202) shaped to couple to electronic device 250 of electronic system 252 can help to efficiently transfer heat to and from electronic device 250. It can be noted that TECs of different shapes are used within the scope of this disclosure.
[0040] In some embodiments, temperature control assembly 200 includes heat transfer assembly 206. In some embodiments, heat transfer assembly 206 efficiently conducts heat energy from the surface of one TEC to the opposite surface of another TEC. For example, to cool electronic device 250 in a test, the bottom surface 204B of TEC 202 removes heat energy (e.g., hot energy) from the top surface of electronic device 250. The top surface 204A of TEC 202 simultaneously generates heat energy, which is transferred via heat transfer assembly 206 to the bottom surface 212B of TEC 210. TEC 210 can remove the received heat energy at the bottom surface 212B of TEC 210. The top surface 212A of TEC 219 can generate heat energy, which is transferred to heat sink 220 and dissipated in the surrounding environment.
[0041] In some embodiments, the heat transfer assembly 206 is made of or constructed of a thermally conductive material. The thermally conductive material includes, but is not limited to, copper, aluminum, brass, or alloys of the foregoing. It may be noted that other thermally conductive materials may be used. It may also be noted that materials with higher thermal conductivity (k) can transfer heat between TEC 202 and TEC 210 more efficiently.
[0042] In some embodiments, the heat transfer assembly 206 includes at least two surfaces 208, including a top surface 208A and a bottom surface 208B. The bottom surface 208B of the heat transfer assembly 206 is coupled to the top surface 204A of the TEC 202. The top surface 208A of the heat transfer assembly 206 is coupled to the bottom surface 212B of the TEC 210.
[0043] In some embodiments, the heat transfer assembly 206 may be coupled to the surface of adjacent components using a thermal interface material, such as a thermally conductive adhesive, thermal grease, phase change material, thermal tape, thermal pad, thermal epoxy resin, etc. For example, the thermal interface material may be disposed between the top surface 204A of the TEC 202 and the bottom surface 208B of the heat transfer assembly 206, and between the top surface 208A of the heat transfer assembly 206 and the bottom surface 212B of the TEC 210. In some embodiments, the thermal interface material may have a minimum electrical conductivity of at least 150 W / m Kelvin (W / mK) or greater.
[0044] In some embodiments, the top surface 208A and bottom surface 208B of the heat transfer assembly 206 may have any number of shapes or sizes. In some embodiments, the heat transfer assembly 206 is tapered such that the top surface 208A and bottom surface 208B are aligned with the surfaces of adjacent TECs (i.e., TEC 210 and TEC 202), respectively. In some embodiments, the top surface 208A and bottom surface 208B of the heat transfer assembly 206 are sized to match or be close in size to the surfaces of the respective TECs. In some embodiments, the top surface 208A of the heat transfer assembly 206 may be of any shape. In some embodiments, the top surface 208A of the heat transfer assembly 206 may be larger than and / or smaller than the surface 212B of the TEC 210. For example, the top surface 208A of the heat transfer assembly 206 may be larger than the bottom surface 212B of the TEC 210 such that the edge of the TEC 210 does not extend over any of the edges of the top surface 208A of the heat transfer assembly 206. In another example, the top surface 208A of the heat transfer assembly 206 may be larger than the bottom surface 212B of the TEC 210 along one axis, but smaller than the bottom surface 212B of the TEC 210 along another axis. For example, the TEC 210 may be longer but narrower than the top surface 208A of the heat transfer assembly 206. In some embodiments, the bottom surface 208B of the heat transfer assembly 206 may be of any shape. In some embodiments, the bottom surface 208B of the heat transfer assembly 206 may be larger than and / or smaller than the surface 204A of the TEC 202.
[0045] In some embodiments, the heat transfer component 206 may be stepped, as shown. In other embodiments, the heat transfer component 206 may have different shapes, such as a planar pyramid shape that gradually narrows from the top surface to the bottom surface. In some embodiments, the shape of the heat transfer component 206 may be partially based on the shape of the TECs that contact the surfaces of the heat transfer component 206. For example, in embodiments using circular TECs, the shape of the heat transfer component 206 may be conical or cylindrical, wherein the bottom and top surfaces of the heat transfer component 206 are circular. In some embodiments, the thickness of the heat transfer component 206 (between surface 208A and surface 208B) is greater than or equal to the thickness of one of TEC 202 or TEC 210.
[0046] In some embodiments, the temperature control assembly 200 may include a heat-conducting layer 214. The heat-conducting layer 214 may include a top surface 216A and a bottom surface 216B. In one embodiment, the top surface 216A of the heat-conducting layer 214 is coupled to the bottom surface 204B of the TEC 202. In some embodiments, the heat-conducting layer 214 can transfer heat energy from the bottom surface 204B of the TEC 202 to the bottom surface 216B of the heat-conducting layer 214.
[0047] In some embodiments, the bottom surface 216B of the thermally conductive layer 214 includes planar regions 260A and 260B (generally referred to herein as "planar region 260"). Planar region 260 may be positioned above one or more electronic devices 250 of the electronic system 252 (e.g., electronic devices 250A, 250B, 250C, and 250E) to transfer heat to the underlying electronic device 250. For example, the bottom surface 216B of the thermally conductive layer 214 may be positioned to couple with the top surface of the package of the electronic device 250 of the electronic system 252, such that the package temperature of the electronic device 250 or the on-chip temperature of the electronic device 250 is controlled to a desired temperature.
[0048] In some embodiments, the bottom surface 216B of the heat-conducting layer 214 may include one or more notched regions, such as notched region 262. In some embodiments, the notched region 262 may be configured such that one or more electronic devices (e.g., electronic device 250D) of the electronic system 252 located directly below the notched region 262 are not coupled to the heat-conducting layer 214. The notched region 262 may allow an air gap between the underlying electronic device and the heat-conducting layer 214, so that heat energy is not transferred between the heat-conducting layer 214 and the electronic device below the notched region 262.
[0049] In some embodiments, the planar region 260 intersects with the notched region 262. The notched region 262 may include a void in the heat-conducting layer 214, extending vertically from the planar region 260 toward the top surface 216A of the heat-conducting layer 214. In some embodiments, the notched region 262 does not vertically intersect the heat-conducting layer 214 from the bottom surface 216B through the top surface 216A (e.g., dividing the heat-conducting layer 214 into two parts). The notched region 262 may leave a portion of the heat-conducting layer 214 above the notched region, such that the heat-conducting layer 214 is a continuous block that efficiently conducts heat.
[0050] In some embodiments, the heat-conducting layer 214 includes four sides, such as a front side, a rear side, a first end, and a second end. A notched region 262 may extend from the front side to the rear side of the heat-conducting layer 214, as shown. In some embodiments, a planar region 260 of the bottom surface 216B of the heat-conducting layer 214 intersects with the notched region 262 to form planar regions 260A and 260B. Planar regions 260A and 260B may be oriented parallel to a plane and oriented at the same vertical distance from the plane. In some embodiments, the notched region 262 of the heat-conducting layer 214 is positioned above at least one electronic device 250 of the electronic system 252 to isolate the respective electronic device 250 (e.g., electronic device 150D) from heat transfer.
[0051] In some embodiments, the notched region 262 may be located at any position along the bottom surface 216B of the thermally conductive layer 214. For example, the notched region 262 may be at an end of the thermally conductive layer 214. In some embodiments, the notched region 262 may be of any size, have any dimensions, and be located at any position relative to the thermally conductive layer 214. In some embodiments, one or more of the size, dimensions, and location of the notched region 262 may be determined based on the location and size of the underlying electronic device that does not require heat transfer.
[0052] In one embodiment, the thermally conductive layer 214 may be coupled to the TEC 202 using a thermal interface material, as described above. In another embodiment, the thermally conductive layer 214 is composed of or made of a thermally conductive material, as described above.
[0053] In some embodiments, the top surface 216A of the thermally conductive layer 214 may have approximately the same size and shape as the bottom surface 204B of the TEC 202. In some embodiments, the size and shape of the surface 216 of the thermally conductive layer 214 may be based on the size and shape of the top surface (e.g., the contact surface) of the electronic device 250. For example, the thermally conductive layer 214 may be shaped such that the bottom surface 216B is coupled to most (if not all) (in some cases, more than the top surface of the electronic device) of the electronic device 250. In some embodiments, the size of the top surface 216A of the thermally conductive layer 214 is approximately the same as, or larger than, the bottom surface 204B of the TEC 202. In some embodiments, the bottom surface 216B of the thermally conductive layer 214 may have the same size and shape as the top surface 216A of the thermally conductive layer 214. For example, the thermally conductive layer 214 may be a cube or a rectangle. In some embodiments, the heat-conducting layer 214 may gradually narrow in one direction or another, for example from the top surface 216A to the bottom surface 216B, or vice versa. It can be noted that the shape of the heat-conducting layer 214 may be at least partially based on the shape of the TEC 202, the electronic device 250, or the electronic system 252.
[0054] In some embodiments, the thermally conductive layer 214 may be an optional element, and the TEC 202 may be coupled to the electronic device 250 to transfer heat to and from the electronic device 250.
[0055] In some embodiments, the temperature control assembly 200 may include one or more thermal sensing devices 218. In some embodiments, the thermal sensing devices 218 may be disposed or embedded within the thermally conductive layer 214. The thermal sensing devices 218 may be located within the thermally conductive layer 214 such that the temperature sensing surface of the thermal sensing device 218 is very close to the bottom surface 216B of the thermally conductive layer 214. In some embodiments, one or more thermal sensing devices 218 may be distributed across the thermally conductive layer 214. The thermal sensing devices 218 can be used to measure the temperature applied to the package of the electronic device 250, which can effectively represent the temperature at the package of the electronic device 250 due to the low thermal resistance (k) of the thermally conductive layer 214. In embodiments, the thermal sensing devices 218 may include any temperature sensing device, such as a thermocouple, a capacitive temperature sensing device, a resistive temperature sensing device, etc. In embodiments, the thermal sensing devices 218 may include a set of wires to couple each thermal sensing device 218 to a measurement unit to measure the output of the thermal sensing device 218.
[0056] In some embodiments, the bottom surface 216B of the thermally conductive layer 214 may comprise a thermal interface material disposed between the thermally conductive layer 214 and the underlying electronic device 250 of the electronic system 252. In some embodiments, the thermal interface material may be one or more of the following: flexible, thermally conductive, compressible, electrically insulating, reusable, and capable of recovering its original shape (e.g., properties) after compression. An example of an interface material having one or more of the aforementioned properties may be a thermal pad. In some embodiments, the vertical height of the electronic device 250 of the electronic system 252 may vary. To couple to electronic devices 250 with different heights, a thermal pad may be disposed between the thermally conductive layer 214 and the electronic device 250 to compensate for the different heights and allow efficient heat transfer between the thermally conductive layer 214 and the electronic device 250. The thermal pad may be compressed between the thermally conductive layer 215 and the encapsulation of the electronic device 250, thereby forming a physical contact between the thermal pad and the underlying electronic device 250, which enables thermal coupling between the thermally conductive layer 215 and the electronic device 250 with different heights.
[0057] In some embodiments, the thermal pad 264 may be applied at least to a planar region 260 of the thermally conductive layer 214. For example, the thermal pad 264 includes thermal pads 264A and 264B corresponding to planar regions 260A and 260B, respectively. In some embodiments, the thermal pad 264 may include a top surface 266A and a bottom surface 266B. The top surface 266A of the thermal pad 264 may be coupled (e.g., bonded) to at least the planar region 260 of the bottom surface 216B of the thermally conductive layer 214.
[0058] In some embodiments, electronic system 252 may have one or more electronic devices, as shown in electronic device 250. Electronic system 252 is shown as a solid-state driver in M.2 form factor. In other embodiments, electronic system 252 may be any type of electronic system or may have any size. In some embodiments, the electronic device is mounted to an electronic circuit board. In some embodiments, one or more of electronic device 250 and electronic circuit board are included in electronic system 252. In some embodiments, one or more of electronic device 250 may include one or more temperature sensing devices, such as on-chip temperature sensing devices. Due to the thermal resistance of the package, the on-chip temperature may differ from the package temperature of electronic device 250. Temperature measurements from the on-chip temperature sensing device, the thermal sensing device 218 of the thermally conductive layer 214, or both can be used to perform thermal testing on electronic device 250.
[0059] In some embodiments, the temperature control assembly 200 may include a heat sink 220. The heat sink 220 may include a top surface 222A and a bottom surface 222B. In one embodiment, the top surface 222A may have a larger surface area than the bottom surface 222B to help facilitate heat transfer from the heat sink 220 to the adjacent medium. In one embodiment, the bottom surface 222B of the heat sink 220 is coupled to the top surface 212A of the TEC 210 to transfer heat from the TEC 210 to the heat sink 220. In some embodiments, the heat sink 220 and the TEC 210 are coupled using a thermal interface material, as described above. In one embodiment, the heat sink 220 is made of a thermally conductive material, as described above.
[0060] In some embodiments, the radiator 220 is a passive mechanical device. In one embodiment, the top surface 222A of the radiator 220 includes a plurality of channels and a plurality of fins disposed on opposite sides of the channels. In other embodiments, the radiator 220 may be another type of radiator, such as a liquid-cooled radiator.
[0061] In some embodiments, the heat sink 220 includes one or more attachment members 224. In some embodiments, the attachment members can be used to secure the temperature control assembly 200 to the hot chamber. In some embodiments, the attachment member 224 is configured to receive an adjustable coupling member 226, which can adjustably couple the temperature control assembly 200 to the hot chamber. In some embodiments, the adjustable coupling member may include a spring element that allows adjustment of the vertical position of the temperature control assembly 200 mounted to the hot chamber.
[0062] In some embodiments, the temperature control assembly 200 may include a fan, such as an electric fan 228. In one embodiment, the electric fan 228 is positioned above the top surface 222A of the heat sink 220 and is used to transfer heat from the heat sink 220 to an adjacent medium, such as the local gaseous medium of the temperature control assembly 200. The electric fan 228 may include a set of wires coupled to a voltage potential.
[0063] For illustrative purposes and not for limitation, a single heat transfer assembly 206 is shown. In other embodiments, multiple heat transfer assemblies 206 may be used. For example, additional heat transfer assemblies may be stacked on the top surface 212A of the TEC 210. The additional heat transfer assemblies may be larger than heat transfer assembly 206. For example, the bottom surface of the additional heat transfer assembly may have approximately the same size as the top surface 212A of the TEC 210. The additional heat transfer assembly may taper such that the top surface of the additional heat transfer assembly is larger than the bottom surface. In one embodiment, the top surface of the additional heat transfer assembly may be coupled to a TEC larger than the TEC 210 (e.g., with a larger surface area). In other embodiments, any number of additional heat transfer assemblies or TECs may be implemented.
[0064] exist Figure 2C In this configuration, temperature control assembly 270 uses a single-layer TEC, such as TEC 272. The heat transfer layer 274 does not contain any notches. Temperature control assembly 270 does not implement a second-layer TEC or heat transfer assembly. Figure 2D In this embodiment, temperature control assembly 280 comprises two TECs at a single level, such as TEC 282A and TEC 282B. It can be noted that the elements of temperature control assemblies 200, 270, and 280 can be mixed, matched, removed, or added to form different temperature control assemblies.

In some embodiments, the adjustable coupling member may include a spring element that allows adjustment of the vertical position of the temperature control assembly 200 mounted to the hot chamber 300.
[0092] In some embodiments, a positive pressure environment is formed within the chamber of the hot chamber 300 using gas injected into the chamber. In some embodiments, instead of hermetically sealing the hot chamber 300, the hot chamber 300 (e.g., the chamber within the hot chamber 300) may be maintained at a positive pressure environment such that the only gas entering the hot chamber 300 originates from a gas port, and the only gas escaping the hot chamber 300 is gas from the gas port. In some embodiments, the hot chamber 300 may include a gas port to receive a gas, such as oil-free air (OFA), nitrogen, or clean dry air or gas (CDA). In some embodiments, the gas may have a dew point below the expected cold temperature range during testing. In some embodiments, the gas may have less than 1 part per million (ppm) of carbon dioxide and less than 0.003 ppm of hydrocarbon vapor. The hot chamber 300 can be used to control the environment near the electronic device 250 during testing. In an embodiment, the gas supplied to the hot chamber 300 has a dew point below the lowest temperature at which the electronic device 250 will be tested. This gas is supplied to the heated chamber 300 so that condensates, such as moisture or ice, do not form at the electronic device 250 during testing. For example, the package of the electronic device under test can be controlled within a temperature range of -25 degrees Celsius to 140 degrees Celsius. The dew point of the gas can be below -25 degrees Celsius (e.g., -90 degrees Celsius). When the temperature control assembly 200 applies a temperature of -25°C to the electronic device under test, condensates will not form at the electronic device due to the low dew point of the gas supplied within the heated chamber 300.
[0093] In embodiments, instead of using hot or cold gases to change the temperature of the hot chamber 300, the temperature control assembly 200 can maintain a local temperature environment for the electronic device 252 under test. In embodiments where the hot chamber 300 includes multiple temperature control assemblies 200 coupled to multiple electronic systems 252, each of the temperature control assemblies 200 can be independently controlled and maintain a different (or the same) temperature at the electronic device of the corresponding electronic system under test, without using hot or cold gases. For example, a first electronic device of a first electronic system under test can be coupled to a first temperature control assembly. A second electronic device of a second electronic system under test can contact a second control assembly. Both the first and second temperature control assemblies can be coupled to a single hot chamber. The first temperature control assembly can maintain the temperature at the first electronic device at 100 degrees Celsius, while the second temperature control assembly can maintain the temperature at the second electronic device at 0 degrees Celsius.
